BAT STRUCTURE.

Specification of Letters Patent.

Patented Jan. 18, 1916.

Application filed May 28, 1915. Serial No. 30,882,

To all/whom t may concern:

Be it known that l, MAXIMILiA'N SCHMITT, a subject of the Emperor ofGermany, re

siding at Paterson, in the county of Passaic and State of N ew Jersey,have invented certain new and useful improvement-s 1n Boat .Structuresof which the following is a specification.

The object of this invention is to provide a canoe or similar boat-likestructure of the class built end for end substantially alike that shallbe capable of being produced by a method considerably simpler than thoseheretofore employed and possess in full measure the usually desiredqualities of grace, symmetry, durability and lightness, together withincreased flexibility, so that it will be especially adapted towithstand shocks and blows incident to the handling thereof'andparticularly to contact With obstacles, such as rocks and the like, Whenafloat.

ln the accompanying drawings, Figure-1 is an underneathplan view of theframe and a mold, assembled, showing a canoe in process of manufacture;Fig. la is a sectional detail of the frame; Fig. 2 is a side elevationof what appears in Fig. l;`.Fig. 3 is a transverse sectional perspectiveview of a fragment of the canoe; Fig 'al shows one of the shell sectionsin inside perspective; and, Fig. 5 is a sectional view on line of Fig.

l provide a skeleton frame which preferably consists of a longitudinalcentral member, a traverse central member and gunwale members. To formthe longitudinalI` member, l employ a liet strip a and the upt-urned orstem pieces a suitably affixed to the ends of the strip a; the parts anda may be formed, desired, all in one piece, but they are preferablyseparate pieces suitably joined, as shown.

To form the transverse member l bend a flat strip l) 'so as to leave itsend portions li standing upright, as shown. To form the gunwales, lprovide'the two strips c c suit-ably shaped to the contour, in plan, ofthe canoe. flhe members c and F) may, if desired, be connected by acheck-joint where they cross (Fig. la). The members c c are suitablysecured to the stems a a and to the upturned ends of the member bearingagainst the inner sides of the latter. Having formed this frame, Ipreferably lit into the same a mold or matrix Z which conforms to theshape of the canoe to be produced, vand which is made sectional so thatit may be removed after the canoe is completed; how the sections of themold are related and removably secured in the frame is not material,though in accordance with the. purpose in utilizing the mold itmay beremarked that it is formed with suitable grooves at e for the receptionof the members a, b and c of the frame, so that they shall be insettherein and havea their outer surfaces iush with the workingr surface ofthe mold. Pieces of veneer, each preferably made upl of layers of-Wood fglued together face to face, the grain of adjoining layers crossing, arethen formed and cut and pressed into pairs of concavo-convex shellsections, the members in each pair of which as to size and shape aresubstantially exact counterparts of each other and at the insidesubstantially exactly fit diagonally opposed portions of the mold. Thesesections g are then secured one after another to the frame inedge-joined relation to each other so that a complete composite shellremains built up on the frame when all have been secured in place; theymay be secured to the frame merlbibers by screws or the like, asindicated at While the mold is not indispensable in the operation ofsecuring the shell sections g to the frame, still it very materiallyassists as a support for said sections while they are being fitted intoplace and secured to the frame.

In the preferred Vconstruction the edgejoining of the sections isaccomplished by beveled lap-joints z' (see Figs. 3 and 4)..

Vhen the shell sections have all been secured in place and, ifnecessary, the joints and edgesthereof finished off smooth and to Ya'shapely form, a coating of duck or the like flexible material j isapplied to the outsidev I of the shell and thenvpainted or otherwisemade waterproof.

Much time and labor are saved by manufacturing canoes and boat likestructures of the kind indicated in accordance with the improved methodherein set forth; besides, the finished product is strong, light anddurable and may be made to possess all the grace and symmetry usuallyrequired in such structures.V My invention makes it possible. further.to reduce the frame structure to the simplest form, as will be obviouson reference to Fig. 1, and l obtain in conblows due to Contact withsubmerged rocks or the like without dalnage'to the shellor other injuryl Having thusfully described my' invention, what I' claim as new anddesire -to sentire by Letters Patent is The hereindescribed boat-likestructure of the class having its fore and aft halves substantialcounterparts of each other including a frame and a composite shellattached to the frame, sald shell Including two pairs of stiff' sheetconcave-convex sections and the sections of each pair being diagonallyopposite to L,each othervand being also sub stantial counterparts ofeach otherin size and shape.

In testimony whereof I affix my Signature.

MAXIMILIAN SCHMITT.
